SVN itself always stores log messages in the repository as
UTF-8. git always stores/retrieves everything as raw binary
data with no transformations whatsoever.
To interact with SVN, we need to encode log messages as UTF-8
before sending them to SVN, as SVN cannot do it for us. When
retrieving log messages from SVN, we also need to (attempt to)
reencode the UTF-8 log message back to the user-specified commit
encoding.
Note, handling i18n.logoutputencoding for "git svn log" also
needs to be done in a future change.
Also, this change only deals with the encoding of commit
messages and nothing else (path names, blob content, ...).

Previously, when 'repack -a' was called and there were no packs in the local
repository without a .keep file, the repack would fall back to calling
pack-objects with '--unpacked --incremental'. This resulted in the created
pack file, if any, to be missing the packed objects in the alternate object
store. Test that this specific case has been fixed.

When the "-v" option is given, we put diff of what is to be committed into
the commit template, and then strip it back out again after the user has
edited it.
We used to look for the diff by searching for the "diff --git a/"
header. With diff.mnemonicprefix set in the configuration, however, this
pattern does not match. The pattern is loosened to cover this case.
Also, if the user puts their own diff in the message (e.g., as a sample
output), then we will accidentally trigger the pattern, removing part of
their output.
We can avoid doing this stripping altogether if the user didn't use "-v"
in the first place, so we know that any match we find will be a false
positive.

Pushing into the currently checked out branch of a non-bare
repository can be dangerous; the HEAD then loses sync with
the index and working tree, and it looks in the receiving
repo as if the pushed changes have been reverted in the
index (since they were never there in the first place).
This patch adds a safety valve that checks for this
condition and either generates a warning or denies the
update. We trigger the check only on a non-bare repository,
since a bare repo does not have a working tree (and in fact,
pushing to the HEAD branch is a common workflow for
publishing repositories).
The behavior is configurable via receive.denyCurrentBranch,
defaulting to "warn" so as not to break existing setups
(though it may, after a deprecation period, switch to
"refuse" by default). For users who know what they are doing
and want to silence the warning (e.g., because they have a
post-receive hook that reconciles the HEAD and working
tree), they can turn off the warning by setting it to false
or "ignore".

Abstract
--------
With index v2 we have a per object CRC to allow quick and safe reuse of
pack data when repacking. This, however, doesn't currently prevent a
stealth corruption from being propagated into a new pack when _not_
reusing pack data as demonstrated by the modification to t5302 included
here.
The Context
-----------
The Git database is all checksummed with SHA1 hashes. Any kind of
corruption can be confirmed by verifying this per object hash against
corresponding data. However this can be costly to perform systematically
and therefore this check is often not performed at run time when
accessing the object database.
First, the loose object format is entirely compressed with zlib which
already provide a CRC verification of its own when inflating data. Any
disk corruption would be caught already in this case.
Then, packed objects are also compressed with zlib but only for their
actual payload. The object headers and delta base references are not
deflated for obvious performance reasons, however this leave them
vulnerable to potentially undetected disk corruptions. Object types
are often validated against the expected type when they're requested,
and deflated size must always match the size recorded in the object header,
so those cases are pretty much covered as well.
Where corruptions could go unnoticed is in the delta base reference.
Of course, in the OBJ_REF_DELTA case, the odds for a SHA1 reference to
get corrupted so it actually matches the SHA1 of another object with the
same size (the delta header stores the expected size of the base object
to apply against) are virtually zero. In the OBJ_OFS_DELTA case, the
reference is a pack offset which would have to match the start boundary
of a different base object but still with the same size, and although this
is relatively much more "probable" than in the OBJ_REF_DELTA case, the
probability is also about zero in absolute terms. Still, the possibility
exists as demonstrated in t5302 and is certainly greater than a SHA1
collision, especially in the OBJ_OFS_DELTA case which is now the default
when repacking.
Again, repacking by reusing existing pack data is OK since the per object
CRC provided by index v2 guards against any such corruptions. What t5302
failed to test is a full repack in such case.
The Solution
------------
As unlikely as this kind of stealth corruption can be in practice, it
certainly isn't acceptable to propagate it into a freshly created pack.
But, because this is so unlikely, we don't want to pay the run time cost
associated with extra validation checks all the time either. Furthermore,
consequences of such corruption in anything but repacking should be rather
visible, and even if it could be quite unpleasant, it still has far less
severe consequences than actively creating bad packs.
So the best compromize is to check packed object CRC when unpacking
objects, and only during the compression/writing phase of a repack, and
only when not streaming the result. The cost of this is minimal (less
than 1% CPU time), and visible only with a full repack.
Someone with a stats background could provide an objective evaluation of
this, but I suspect that it's bad RAM that has more potential for data
corruptions at this point, even in those cases where this extra check
is not performed. Still, it is best to prevent a known hole for
corruption when recreating object data into a new pack.
What about the streamed pack case? Well, any client receiving a pack
must always consider that pack as untrusty and perform full validation
anyway, hence no such stealth corruption could be propagated to remote
repositoryes already. It is therefore worthless doing local validation
in that case.

Diffs that have been produced with textconv almost certainly

This introduces a new diff options, ALLOW_TEXTCONV, which
controls this behavior. It is off by default, but is
explicitly turned on for the "log" family of commands, as
well as the "diff" porcelain (but not diff-* plumbing).
Because both text conversion and external diffing are
controlled by these diff options, we can get rid of the

The original implementation of textconv put the conversion
into fill_mmfile. This was a bad idea for a number of
reasons:
- it made the semantics of fill_mmfile unclear. In some
cases, it was allocating data (if a text conversion
occurred), and in some cases not (if we could use the
data directly from the filespec). But the caller had
no idea which had happened, and so didn't know whether
the memory should be freed
- similarly, the caller had no idea if a text conversion
had occurred, and so didn't know whether the contents
should be treated as binary or not. This meant that we
incorrectly guessed that text-converted content was
binary and didn't actually show it (unless the user
overrode us with "diff.foo.binary = false", which then
created problems in plumbing where the text conversion
did _not_ occur)
- not all callers of fill_mmfile want the text contents. In
particular, we don't really want diffstat, whitespace
checks, patch id generation, etc, to look at the
converted contents.
This patch pulls the conversion code directly into
builtin_diff, so that we only see the conversion when
generating an actual patch. We also then know whether we are
doing a conversion, so we can check the binary-ness and free
the data from the mmfile appropriately (the previous version
leaked quite badly when text conversion was used)
